The first step to changing 20 15/5 into a decimal is to change it to an improper fraction. To do that, we need to multiply 20 by 5 and add its product to 15 in the numerator to get: 115/5. Now we will attempt to convert 115/5 to a decimal using the following method.
A fraction is written in terms of two parts: the number on top is called the numerator and the number on the bottom is called the denominator. We can use the division method to solve this question. To get a decimal, simply divide the numerator 115 by the denominator 5:
115 (numerator) ÷ 5 (denominator) = 23
As a result, you get 23 as your answer when you convert 20 15/5 (or 115/5) to a decimal.
